Wemos and DHT22 readings on an OLED display simple project

In this particular example we are going to simply display temperature. pressure and altitude readings from a DHt22 sensor on an OLED display. These are all the shields used in making this a simple project to build.

Requirements

1 x Wemos Mini
1 x Wemos Dual Base
1 x OLED Shield
1 x DHT Pro Shield

You can see what I assembled in the picture below, I could have stacked in one column but I wanted to see the OLED and also leave the DHt22 uncovered.

Code

Various libraries required – you can install these via the library manager, here are links to them
